I'm trying to become an online math tutor. One of the website's policies is that tutors must pass exams for classes that they wish to teach. You have to answer a certain number of questions correctly before the time runs out, and you only get two chances per exam. I want to teach mid-level math for grades 7-8, but I already failed once because I ran out of time. Speed has always been an issue with me, especially when it came to schoolwork. I'm certain that I know the material, but I need to prove it by giving the right answers more quickly. Some of you might think that I could be setting my expectations too low if you knew that I graduated with a BS in Math, but I want to work my way up from teaching simple math to the more difficult topics so that I don't overwork myself too soon or too quickly. So, does anyone know some good websites that will allow me to practice answering math problems quickly for free?
